New preterm formula study: will HMOs help tiny babies grow?
NCT ID NCT04639518
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested two types of preterm infant formula—one with added human milk oligosaccharides (HMOs) and one without—to see how they affect growth and safety in very small babies. Twenty-eight preterm infants weighing 1.5 kg or less were enrolled. Researchers tracked weight gain, length, and head growth from birth until two months after hospital discharge.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Preterm infant formula (with or without human milk oligosaccharides)
- What this could lead to
- If successful, this could help doctors choose safer, more effective formulas for preterm babies to support healthy growth.
- What could go wrong
- This is a small, early-stage study with only 28 infants, so results may not apply to all preterm babies. Formulas are not a cure and only support nutrition.
